,An. object of the ,inventionis to afford, a dis 'pensing attachmentfora liquid container, said attachment andthe container being formed soas to be connected together and become'operable for withdrawal of smallquantities of liquid from the container when the attachment iscompletely seated and securedon the container, and'become Vinoperativewhen loosely orpartially connected.

fording a chamber 8 therein above the-neck of the'base, saidborehavingra-continuation 9 of reduced diameter that. extends-from saidchamber through the top of thec'asing. In the lower end of the smallerbore'is securely positioned a tubular-valve seat! on which rests anoutflow check-valvell that isnorm'ally closed. A second vtubular valveseat" 12 i securely positioned in the smallbo're in the casing:upon'which rests a second outflow check-valve I3 that is normallyclosed. The'lower' end of the tube l2 terminates at a point spac'edfromthecheck valve ll and has made therein a notch Mwhereby the check-Another object of the invention is toprovicle 1 a dispensing applianceconnected separably with a liquid container, bothof which are soconstructed asto be .,co-operative when connected together, and.,.non-interchangeablex with other differently constructed similarappliances and containers, the purpose bein to circumvent use of partsof the instant invention indiscriminately with parts of otherapparatuses l And a further object of the invention is the provision'ofa dispensing. device having a suction tube and related parts arrangedsoithat when the body of the dispensing device is secured to a liquidcontainer communication between the tube and the discharge channelof-the dispensing device is established to' render the apparatusoperative. Other objects and advantages'of the invention appear in thefollowing description; ,An illustrative embodiment of the 'inventioniisshown inthe'accompanying drawing, in which: Fig. 1 is aside'elevationalview of a structure in which-the invention is incorporated, partsthereof being broken away; and v Fig. 2 is a similar view'of thedispensingappliance shown in Fig. 1, attached to a liquid container inoperative position, portions being broken away; i I

The illustrative embodiment of the invention consists of a detachabledispensing device formed of a base member] having a tubular neck 2 andan internallythrea'ded lower end3 constituting a cap adapted to fit ontotheexternally threaded. neck 4 of a liquid container 5, therebeing avent opening S-made in the base that affords an inlet for airtothe'container forthe relief of vacuum created therein as liquid from thecontainer is withdrawn by the appliance.

Upon the neck 2.--is closely fitted a valve casing 1,- the lowerend-portionpof, which has abor'e'iaf valve rl-l ispr'evente'dfromclosing the tube l2 when the check-valve I lis-unseated by outflowof liquidthrough'the tube- It]; 2

A'hollow stem I1 is secured in'oneuside of -the casing I that hascommunication with the bore of, the tube. I-2- through a passagewaygl8therein, and the outer end of 'said stem has secured thereon acompressible bulb 19, upon manipulation 'ol which, altemateoutfiowthrough the spout and check-valvesl l an'd l3'takes place. i 1 I r r'Theypassageway 'l8 inthe tube 12 is located preferably'at "a pointabove the axis of the'stem 12 so" that seepage of liquid fromthebulbback into the tube'l2" is limited'and loss "of prime is thussubstantially averted. This arrangement is desirable especiall'y'whenthe applianceis'=leftidle for a consi'derableperio'd of time betweenopery Preferably, a metallic band 291s disposed about the valve casing1, through oneside' of which the stemiz l 1' projects, the'band"serving" as an orna-f mentation as well-as to strengthen the casing.'
